COIVIBINED HEATER AND RADIATOR.

Specification of Letters Patent.

Patented Sept. 27, 1910.

Application filed. February 3, 1909. Serial No. 475,752.

To all whom it may concern:

Be it known that I, ELAM V. Bnn'rnnr, a citizen of the United States,and 'a resident of Everett, in the county of Snohomish and State ofWashington, have invented a new and Improved Combined Heater andRadiator, of which the following is a full, clear, and exactdescription.

The purpose of this invention is to provide novel details ofconstruction for a heat radiating stove that may be readily convertedinto a cooking stove, the device being well adapted for consuming liquidfuel or coal by slight changes in construction.

The invention consists in the novel construction and combination ofparts, as hereinafter described and defined in the appended claim.

Reference is to be had to the accompanying drawings forming a part ofthis speciti cation, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a side elevation of the device. arranged a heat radiator;Fig. is a sectional side view, taken through the longitudinal center ofthe heat radiator shown in Fig. 1; and Fig. 3 is a transverse sectionalview, substantially on the line 33 in Fig. 2.

In carrying into effect the features of the invention, any availablematerial may be utilized, and the shape thereof may be considerablymodified within the scope of the invention. In the example herepresented, plate metal is employed, which is preferably cut and bentinto form as represented in the drawings, which will now be described.

The preferred fuel for the evoluton of heat, is liquid, such askerosene, gasolene or alcohol, which may be consumed in a suitableburner fed by a wick, that is supplied with said combustible from areservoir.

In the drawings, 10 indicates a liquid holder, that is cylindrical andmay be of any preferred dimensions, said holder or tank having a fillerorifice in its upper side, normally closed with a screw cap a orequivalent means.

There are a plurality of burner tubes b projected from the upper side ofthe tank 10, that contain wicking c, as indicated in Fig. 3, said tubesbeing spaced from each other; and as represented, the wicks may beadjusted in the usual manner by thumb wheels (Z on the ends of shafts dthat enter the side of the tank, and as this is a common means forregulating the height of the wicks, it is not considered necessary tofurther illustrate this minor detail.

The tank 10 is supported concentrically within a cylindrical wall 11,which is the base section of the combined heater and radiator. Upon theupper edge of the base section 11, a top wall 12 therefor detach ablymounted and removably secured by means of a depending peripheral flange12, that is secured upon the edge of the top wall and fits loosely uponthe exterior surface of the base section when the top wall is mountedthereon. Centrally in the top wall 12, acircular opening is formedwherein is fitted and secured the lower edge of a deflector cone 1%,that projects upward through said opening. 'lhere is an upwardlyprojecting peripheral flange 0 formed on the edge of the top wall 12,and may be integral with the flange 12, said flange 6 serving to hold inplace a coacting second section that is constructed as follows.

A plate metal coniform wall 13, that at its lower end is provided withan imvardly turned flange, has such a relative diameter at said lowerend as adapts it to lit loosely within the upturned peripheral flange 0when the flange on the wall 13 is seated upon the top wall 12. It willbe seen in Fig. 2 that there is an annular space or channel it formedbetween the central cone 12 and the coniform wall 13, when the latter isin position 011 the top wall 12; and furthermore, that the burners Z)are so relatively positioned that flame therefrom will impinge upon theinner surface of the coniform wall 13 and spread thereover and quicklyheat said wall, that converges the annular heat current as it passesupward.

Cooperative with the base section 11 and coniform section 13, is a thirdsection, comprising the following details: Upon the lower edge of aninverted coniform wall 14'. that is formed of plate metal, is allixedthe upper edge of a circular downwardly flaring wall 143, these firmlyconnected walls being held so as to give the lowermost wall ll a centralposition in the annular space 72, by angular braces i, that arerespectively secured upon the inverted coniform wall l l near its lowerend and the upper portion of the coniform section 13, as is indicated inFig. l.

A downwardly converging deflector cone 15, is centrally and verticallysupported and positions given to the secured in the inverted coniformwall let, by an impingement of its lower end as at m, upon the apex ofthe deflector cone 12 and securing U-shaped braces 71 between the inverted coniform wall 1a and the deflector cone 15 near their upper ends.The upper end of the deflector cone 15 may be closed, as shown at 15*,and on said top wall a handle piece 0 is secured, which affords meansfor placing the third section in position on the top wall 12 or removingit therefrom.

It will be noted in Fig. 2 that the relative opposed deflector cones 12and 15, and the coniform walls 1% and 1% that have a common axis, whenthe third section is in position on the top wall 12, affords an annularcentrally converged air passage 7) between the cones and concentricwalls 14, lt which passage extends from the top wall 15" to the lowerend of the flaring wall 14-, which end is spaced from the top wall 12 soas to permit an air passage 1' therebetween.

In the operation of the apparatus hereinbefore described, assuming thatliquid fuel in suliicient amount has been placed in the tank 10 and thewicks c are lighted, the flame therefrom will impinge upon the innersurface of the coniform wall 13 and trend upward through the annularchannel /2, the evolved heat current enveloping the outer surface of thedepending converged wall lat. This heat current will create a partialvacuum ,in the inner annular air passage 2), which wilf induce adownward air current therethrough, this air current becoming highlyheated by its intimate contact with the flames from the wicks c, and itwill be noted that the rarefied and hot air that impinges upon the wall141, will be deflected therefrom into surrounding space and warm the airtherein.

It is claimed that the details of construc tion for a combined heaterand radiator herein set forth, are cooperative and aflord a compact,inexpensive, and practical apparatus for the purpose specified.

It will be evident from the description, that applicants radiating meanscomprises a pair of spaced concentric frusto conical rings, a secondpair of spaced concentric frusto conical rings arranged above the firstnamed rings and with their apexes down ward, the outermost ring beingprovided with a petticoat extending between the first named rings.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

In combination, a liquid fuel supply tank, burners thereon, a casingsurrounding the tank, a top wall on the casing having an uprightperipheral flange thereon, and also having a central conical deflector,an inverted conical deflector vertically supported on the apex of thefirst-mentioned conical deflector, an upwardly converged coniform wall,a downwardly converged coniform wall mount-ed upon the first-mentionedwall and secured to the inverted conical deflector, said converged wallsbeing spaced from the cone deflectors and afl'ording an annular airpassage therebetween, and an upwardly converged coniform wall seatedupon the top wall of the casing and spaced from the first named upwardlyconverged coniform wall, affording a conduit for the heat current fromthe burners, which current envelops and heats the upper invertedconiform wall, from which the heat is radiated.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ELAM V. BENTLEY.
